As to Kidani, see this map file:///Users/don/Desktop/Kxq3nYU.jpg The standard view rooms that have savanna view are (a) all rooms on the Pembe savanna side in the sixth and seventh building units from the lobby on the north wing; the Pumbaa elevator is between those two building units; (b) about half the rooms on the Pembe savanna side in the fourth building unit on the north wing are standard views with at least partial savanna view. Best request to make to get savanna view with a standard is likely to request a room near the Pumbaa elevator.
As to Jambo see this map for location of standard view rooms
G2qaSva.png. More than half the standard view rooms have savanna view while the rest overlook the pool area. Best request to make to get a savanna view with a standard view room is to request a room on the Kudo Trail side of the building (the left side of the u-shaped building when facing the map) because all standards on that side have a savanna view (of the Sunset savanna).
